And a check valve is arranged at the outlet of the air compressor, so that condensed water in the aeration pipe is prevented from being sucked back into the air compressor to damage the air compressor.

The aeration disc holes are uniformly formed in the upper side and the lower side of the bracket, and the aeration discs and the aeration disc holes are correspondingly arranged into four groups and uniformly distributed at the bottom of the pool body.

The aeration disc adopts a micropore aeration disc for aeration.

Dissolved oxygen in the pool body needs to be kept at 2-4mg/L and is controlled by the air inlet valve.

The bracket is made of UPVC, and the air inlet pipe and the aeration pipe are made of stainless steel.

The utility model has the advantages that the flange connection is arranged between the air inlet pipe and the aeration pipe, so that the disassembly is convenient, when the uneven aeration phenomenon occurs or the condition of the aeration disc is regularly checked, the bracket can be integrally lifted to the outside of the tank body through the disassembling flange, and the maintenance and the replacement of the aeration disc are convenient; meanwhile, the integral mounting structure of the aeration disc in the prior art is improved into a plurality of independent brackets with small structures, so that each bracket is convenient to lift.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3, the liftable aerobic tank aeration system of the present invention comprises a tank body 1, an aeration disc 6, an air inlet pipe 8 and an aeration pipe 3, wherein a plurality of brackets 10 are arranged inside the tank body 1, aeration disc holes 9 are uniformly arranged on the upper and lower sides of the brackets 10, and the aeration disc 6 is arranged on the aeration disc holes 9; an air inlet 7 is further formed in the center of the bracket 10, one end of the air inlet pipe 8 is fixed to the bracket 10 and communicated with the air inlet 7, the other end of the air inlet pipe is connected with the aeration pipe 3 through a flange 5, and an air compressor 2 and an air inlet valve 4 are sequentially installed on the aeration pipe 3 along the air inlet direction.

The outlet of the air compressor 2 is provided with a check valve 11, so that condensed water in the aeration pipe 3 is prevented from being sucked back into the air compressor 2 to damage the air compressor 2.
